What you need to do is find a photograph or a sketch of a particular pose/look/feel that you want. Take that to your artist and have them draw it up for you.

If you're looking for an actual tattoo to base it on, it will be a lot harder to find and your artist should be able to work with whatever you take them anyway. It doesn't have to be a picture of a tattoo.
